Plants have a remarkable ability to coordinate cellular activities across huge distances, yet we have only a basic understanding of how these remote activities are coordinated. A review by Rodrigues et al. summarizes what we know about the relationship between source (e.g., photosynthetic tissues) and…

Plant morphogenesis is a dynamic process that can be modulated in response to environmental cues. In this work, Xiao et al. characterized germination and seedling development in date palm. After germination, the cotyledonary petiole grows, but the embryo development is paused. At early stages of development…

Domestication has been accompanied by a decrease in genetic diversity, so efforts to improve stress tolerance can be aided by exploring the crop’s wild relatives. Here, Pailles et al. examined salt tolerance in Galapagos tomatoes (Solanum cheesmaniae and Solanum galapagense), which grow “constantly…

Arsenic contamination is a growing human health threat. The fern Pteris vittata demonstrates a remarkable capacity to accumulate and sequester high levels of the toxic heavy metal arsenic from contaminated environments. Cai et al. used an ‘omics’-guided approach to identify and characterize the molecular…

The agriculture sector is going to face big challenges to feed the 10 billion people that are going to inhabit the planet in the upcoming years with limited arable land. One effective practice to enhance the yield per unit area is to increase crop planting density. However, in dense stands, plants…

As plants are sessile organisms, they have developed highly sophisticated mechanisms to allow the modulation of development in response to environmental changes, thus maximizing their chance of survival. When soil dries, soybeans with a slow canopy wilting (SW) phenotype have delayed canopy/leaf wilting…

Non-directional stimuli can trigger directional movements in plant organs. For instance, high temperature causes the upward bending of leaf petioles, a process known as leaf hyponasty, which helps to cool the leaves. In this study Park et al. explored the link between leaf thermonasty and auxins. Gene…

“Earth is a cold place with 80% of its biosphere permanently below 5°C,” begins this study of an Antarctic psychrophile (“cold-lover”). As Szyszka-Mroz et al. indicate, the permanently cold-adapted inhabitants of permanently frozen lakes are highly vulnerable to the effects of climate change,…
